I'm writing a story that involves a character dying from a head injury. The character received a few blows of blunt force trauma to the head, which I believe causes a focal brain injury(is that correct?). I was then planning on having the character be taken back to the hospital, where they would remain unconscious, and then die a few hours later. What treatments would the doctors give the patient? And what complications of the injury would cause her to die a few hours later? I was thinking some kind of hemorrhage or something, but I don't know if that would happen a few hours later or just immediately after the trauma. Any fatal complication will do; I just need her to die a few hours after the initial injury. Also, the patient is a young child. I don't know if that makes a difference or not.
Any feedback anyone can give me would be appreciated.
ETA: I tried to do a little bit of research on my own. Not sure how valid all the information is, but I read the wikipedia pages for traumatic brain injury, focal and diffuse brain injury, concussion, and skull fracture.
